Endangered Species in the US: Complete 2025 List & Protection
The endangered species in the US face unprecedented challenges as habitat loss and climate change accelerate extinction rates. Currently, over 1,600 species are listed under the Endangered Species Act, with many requiring immediate conservation action. From the iconic California condor to lesser-known plant species, America’s biodiversity crisis demands urgent attention to preserve these irreplaceable natural treasures for future generations.
What Are Endangered and Threatened Species in the United States
Under the Endangered Species Act of 1973, endangered species are those at risk of extinction throughout all or a significant portion of their range. Threatened species are likely to become endangered in the foreseeable future. The US Fish and Wildlife Service maintains the official endangered species list, which includes over 1,600 species as of 2025.
The classification system helps prioritize conservation efforts and allocate resources effectively. Endangered species in the US receive the highest level of protection, including habitat designation and recovery plans. The Act has successfully prevented extinctions and facilitated recoveries, with notable successes like the bald eagle and gray whale removals from the list.
Top 10 Most Endangered Species in the US 2025
The most endangered species in the USA represent diverse ecosystems across the nation. These critically threatened animals and plants face immediate extinction risk without intensive conservation intervention.
Marine and Aquatic Endangered Species
The North Atlantic right whale leads marine endangered species with fewer than 340 individuals remaining. Endangered species in the US waters also include the Hawaiian monk seal, Florida manatee, and various salmon populations. These marine mammals face threats from ship strikes, entanglement in fishing gear, and habitat degradation affecting their critical feeding and breeding areas.
Terrestrial Endangered Wildlife
The Florida panther remains one of the rarest animals in the United States with approximately 200 individuals. Other critically endangered terrestrial species include the black-footed ferret, red wolf, and California condor. These species require extensive habitat management and breeding programs to maintain viable populations in their native ranges.
Complete Endangered Species List by Region
North American endangered species vary significantly by geographic region, reflecting unique ecosystems and environmental challenges. The Pacific Northwest harbors different threatened species than the southeastern wetlands or Great Plains grasslands.
Western United States Endangered Species
The western states host numerous endangered species in the US including the California condor, desert tortoise, and various salmon runs. Habitat loss from urban development and agriculture poses significant threats to these species. Water scarcity and climate change particularly impact desert and mountain ecosystems throughout California, Nevada, and Arizona.
Eastern United States Threatened Wildlife
Eastern endangered species include the Indiana bat, Karner blue butterfly, and numerous plant species in Appalachian forests. Habitat fragmentation from development and invasive species pressure threaten these populations. The red wolf recovery program in North Carolina represents one of the most intensive conservation efforts for eastern endangered mammals.
How Many Endangered Species Are in the US Currently
As of 2025, the United States has 1,662 species listed as endangered or threatened under federal protection. This number includes 1,203 endangered species and 459 threatened species across various taxonomic groups. Endangered species in the US encompass mammals, birds, reptiles, amphibians, fish, invertebrates, and plants representing America’s biodiversity crisis.
The distribution shows 423 endangered animal species and 780 endangered plant species, highlighting that flora faces greater extinction pressure than fauna. Recent additions to the endangered species list include the tricolored bat and several freshwater mussel species, reflecting ongoing environmental pressures across different habitats and ecosystems.
Why Species Become Endangered in America
Habitat destruction remains the primary cause of species endangerment, affecting over 85% of endangered species in the US. Urban development, agricultural expansion, and infrastructure projects fragment natural habitats, reducing available space for wildlife populations to maintain viable breeding communities.
Climate Change Impact on US Wildlife
Climate change accelerates endangerment for many North American endangered species through shifting temperature and precipitation patterns. Rising sea levels threaten coastal habitats while changing weather patterns disrupt migration timing and breeding cycles. Arctic species like polar bears face particular challenges as ice habitats diminish.
Invasive Species and Disease Threats
Invasive species introduction creates competition and predation pressure on native endangered species. Diseases like white-nose syndrome in bats and chytrid fungus in amphibians have devastated populations. These biological threats often combine with habitat pressures to push vulnerable species toward extinction.
Success Stories in Endangered Species Recovery
The Endangered Species Act has facilitated remarkable recoveries for several species previously on the brink of extinction. The bald eagle population recovered from 417 breeding pairs in 1963 to over 316,000 individuals today, leading to its removal from the endangered list in 2007.
California condors increased from 27 individuals in 1987 to over 500 birds as of 2025 through intensive breeding and release programs. Endangered species in the US benefit from dedicated recovery efforts combining habitat protection, captive breeding, and threat reduction strategies that demonstrate conservation success is achievable with sustained commitment.
Current Conservation Efforts and Protection Programs
Federal agencies coordinate extensive conservation programs for endangered species in the US through habitat acquisition, research funding, and partnership initiatives. The US Fish and Wildlife Service manages National Wildlife Refuges specifically designed to protect critical habitats for endangered species across diverse ecosystems.
Private landowner incentive programs encourage voluntary conservation on private lands where many endangered species depend on habitat outside federal protection. These collaborative approaches recognize that successful conservation requires partnerships between government agencies, non-profit organizations, academic institutions, and private stakeholders working together toward common conservation goals.
How You Can Help Protect Endangered Species
Individual actions contribute significantly to endangered species protection through habitat conservation and sustainable lifestyle choices. Supporting wildlife-friendly agriculture, reducing pesticide use, and creating pollinator gardens help protect species habitats in local communities.
Participating in citizen science projects provides valuable data for researchers studying endangered species in the US. Volunteer opportunities with conservation organizations offer hands-on involvement in habitat restoration, species monitoring, and educational outreach programs that raise awareness about biodiversity conservation needs in local and regional ecosystems.

Questions & Answers
What is the most endangered species in the USA?
The North Atlantic right whale is considered the most critically endangered marine mammal with fewer than 340 individuals remaining. On land, the Florida panther with approximately 200 individuals and the California condor with around 500 birds represent the most endangered terrestrial species requiring intensive conservation management.
How many endangered species are in the US?
As of 2025, there are 1,662 species listed as endangered or threatened under the Endangered Species Act in the United States. This includes 1,203 endangered species and 459 threatened species, encompassing mammals, birds, reptiles, fish, invertebrates, and plants across all major ecosystems.
What is the rarest animal in the United States?
The Florida panther is among the rarest animals in the United States with only about 200 individuals remaining in the wild. The species is found exclusively in southwestern Florida and represents one of the most endangered large mammals in North America requiring ongoing conservation efforts.
What are the top 10 most endangered animals in the US?
The top 10 most endangered animals include the North Atlantic right whale, Florida panther, California condor, black-footed ferret, red wolf, Hawaiian monk seal, Amur leopard, vaquita porpoise, Javan rhinoceros, and cross river gorilla.
